What comparison does the Satcharitra make between the passing of a saint and the birth of a god?

In its description of Sai Baba's Mahasamadhi, Chapter 42 draws a poignant distinction between how saints and gods are commemorated. While discussing the day of Baba's departure, which was Vijayadashami, the text notes, "While that day was Buddha Jayanti for some, it was the death anniversary (Punya Tithi) for Sai." It then makes a generalized spiritual statement: "The birth anniversary of gods is the death anniversary of saints." This suggests that for a saint, the moment of leaving the physical body is a celebrated, sacred event of liberation, akin to how a god's birth is celebrated.
